CAN-COVER.

' Application filed May 9,

To all whomitmay concern: v

Be it' known that I, JAMES R. PRATT, citizen of the United States,residin' at enison, in the county of Grayson and 1 late Texas, 1 i andliquids and refers more especially to vessels applied to the opening andremoved rovidedwith stopping the filling constructed of metal screw orslip caps for orifice.

The chief objects of my invention are to I provide a can closure thatcan be readily thererom, such closure having retaining means orpreventing its displacement or loss; and to furnish a connecting meansadapted to secure the cap or stopper to the mam body of the vessel andat the same time permit a sufficiently free moveu'lent of the cover toprevent interference with the insertion of a cup having 1s specificationandin which: Figure 1 1s a sectional view of showing a retaining insidethe cap a can top, device located entirely Figs. 2 and 3showmodifications of the attachment illustrated in Fig. 1

to engage the threads of said nipple and is urnished with a lug 11'fixed in the center of the top of the cover. To this lug is piv- Iotally attached a connectlng member 12 bent {at a right angle at thepoint 13 to form a. vertical portion 14 which passesfreely through holesin the flanges 15 of a bracket f 16 secured to the inside assembling theparts the lower free extremity I of the vertical arm 14 is bent into anI. formed with a simple angle 17 to prevent its ecoming disengaged fromthe bracket flanges.

It will be seen that the device is entirely the nipple 7 in engagementtherewith. The Vertical portion 14 is made of suflicient length in allthe. forms shown to allow the cap to beelevated high enough to permit itto clear the nipple atter which it can be swung upon the centers ofmotion quickly replaced upon its seat and is sufii ciently out of theway to allow the introduction of a funnel or tube into the orifice.

It will be readily understood that the conmeeting member has a pivotalconnection with the cover center for the two fold pur 0% of permittingthe necessary rotary motion to-be given to the said cover to engage anddisengage it from its threaded scat upon 7 the nipple. In the modifiedform it may sometimes be considered desirable to remove the cap so as tobe entirely displaced from the nipple and thus avoid any interferencewith a free opening. For this purpose I have designed the modificationsillustrated in 3. In the former case the lug 11 is replaced by an Lshaped rod or stem 18 projecting downward from the under surface of theheap 8, the-upright'memher 14 of the con necting link engaging amodified form of bracket '19 which of the can, which is to-encroach uponthe opening of the nipple, an orifice 22 being formed for the passage ofthe liquid contents of the can. In the case thus illustrated the ca maybe swung away f om the nipple after lieing 1121- Figs. 2 and to allowopening in said arm contracted to a round hole for the passage of thestern as in the other cases shown. A further advantage in this form liesin the fact that the vertical member 14 is shortened so that it does notextend below' the nipple and this formfof connection can thus heused'whether the to of the can body does or doesnot encronc upon theopening of'the nipple skirt, since it needs only the single point ofsupport 19.

In all the modificationshereinbefore described the caps shown therewithhave been provided with screw connection with the thinihle or nipple ofthe can. In Fig. 4 is illustrated an adaptation of the connecting devicefor use with a slip ca 23 which en} gages the external surface 0 an oilon 2a the stem 25 being located eccentricall in the top of thecap andextending interiorly thereto, being permanently attached to the cup by aclip 26 which perinitsfree play to said stem, the latter being ofsuiiicient length the cover or cap to he slipped free from its seat,when it can be rotated to the position shown in dotted lines.

While I have shown my improved can closure adapted tocertain forms ofnipples and applied to the filling apertures it is evident that thedevice is equally applicable to containers of different design, and thedischarge orificesas well, without departing from the spiritand scope-ofthe invention and I do not wisln'therefore, to be limited in itsapplicatiomnor to the precise details of construction and applicationset forth.

Having thus described my invention what I claim as new is l. Incombination with a container having a suitable neck, a closure,consisting of ceases a ca adapted to fit said neck, perforated gui esecured to the inner surface of said neck, a bent arm pivotallyconnectedwith the inner surface of saidcap, and having a ide.

2. In combination with a container hav ing a threaded extension, a capadapted to enga e said extension, a bent arm arranged within saidextension, and pivota'iiy engag ing the center of said cap, a guidesecured within said,container and having alined openings therein, andmeans connecting said arm and guide said means adapted to permit the capto be turned on its vertical axis, to be raised and lowered relative tosaid container and to be swung toward and away from said extension,substantially as set forth.

3. In combination with a container having an extension with an openingtherein,

a cap for saide'xtension, and means attaching said ,cap'to'saidextension said means consisting of 'a'bearin'g arranged within saidcontainer, a rod slidably mounted in said beari and havin a stop thereonand means pivota y and slidiiblyconnecting said cap with said rod.

4. A device for securing a's'crew @ip to a conta ner, consisting of abearing R18C6'887 cured to said: container, an arm pivotally mounted insaid bearing and having anelongated eye formed therein, and meansconnecting said eye with the top of the cap, said means adapted to-limitthe vertical movement of the cap relative to the container. v

'5. In means for securing a screw-cap to a container, a rod secured tothe cap and depending therefrom within the container, means on said rodfor limiting the vertical movement of said cap relative to-thecontainer, and means connecting said rod with' said. container, andadapted to 'permit the rotation ofsaid cap on said container.
